Bloggers, Twitter users, and TechCrunch are reporting that certain Gmail accounts are marking incoming messages as "read" upon delivery, leaving inboxes apparently, falsely empty. Google's Apps Dashboard isn't reporting any problems as of this post, but a blogger reports the problem as IMAP-related, and offers this advice for IMAP users: " ... set the PEEK mode to TRUE if you get an (e)mail's BODY from Gmail." If you've experienced this issue yourself, and maybe verified a fix for it, share it with your fellow Gmail users in the comments.
